What is the term for when a school bus is stopped behind a vehicle and the driver can see the tires touching the ground?

The correct answer refers to the concept of a "space cushion," which is the buffer of space that a driver maintains around their vehicle. This space is crucial for providing the driver with enough time and distance to react to any potential hazards on the road.

In the context of a school bus, when the driver can see the tires of the vehicle in front touching the ground, it indicates that there is an adequate space cushion between the bus and the vehicle. This allows the driver to assess the situation and react accordingly, whether it be preparing to stop, accelerate, or maneuver safely.

Maintaining a space cushion is an essential practice for ensuring safety, as it reduces the risk of rear-end collisions and gives the driver a better view of the road ahead. In the case of school buses, this practice is even more critical due to the presence of children loading and unloading, as well as the need for the bus to stop frequently.

The other options, such as "safe zone," "driver space," and "stopping distance," do not accurately describe the situation of seeing the tires of the vehicle in front. A safe zone refers more broadly to areas where pedestrians can be safe from vehicles, driver space doesn't specify a clear concept related to the scenario, and
